Installation Requirements
1. Plumbing
Read the section 'Important Safety Information' first.
1.1The Elite ST is designed to operate with water supply pressures from 0.8 kPa
(0.008 bar / 80 millimetres head) to 100 kPa (1 bar / 10 metres head) (i.e. the
vertical distance from the base of the cold cistern to the top of the Elite ST).
However, the minimum head required will increase with pipe length and the
guide given in paragraph 1.17 should be used to make sure that adequate head
is available for any given installation.
The Elite ST MUST have its own separate supply from the cistern.
25 Gallon/113 Ltr Cistern
Correct Cistern Take Off
25 mm
Positioned away from the ball
valve, with a 25 mm distance
up from the base of the
cistern. This connection will
prevent air and debris entering
the shower supply.
Incorrect Cistern Take Off
Debris from the bottom of the
cistern and air generated when
the cistern refills will enter the
shower supply.
1.2 The Elite ST is suitable for installation within the shower area and is fitted with
a pressure relief valve. It must be positioned over a water catchment area with
the controls at a convenient height. The shower fitting should be positioned so
that it discharges down the centre line of the bath, or across the opening of a
shower cubicle, and must be directed away from the shower unit.
1.3 Use a minimum of 15 mm diameter supply pipework. It should be noted, however,
that on long pipe runs this should be increased to 22 mm (refer to para 1.17 for
guidance). When using flexible plastic pipe it is essential that the pipe is kept
flat and not looped up at any point as this may lead to air build up which may
impair performance of the shower.
1.4 A non restrictive (free flowing) isolating valve should be fitted into the supply
from the cold water cistern, for maintenance purposes.
1.5 The Elite ST must be fitted onto the finished wall surface i.e. on top of the
tiles. Do not block the air ventilation gaps around the sides of the unit, either
by tiling up to the sides of the unit or by using a sealant around the case.
Important! This Elite ST is designed to be ventilated. Failure to do this may
cause product failure.
Note! The Mira Elite ST is fitted with a pump motor, and some mechanical
noise can be expected in addition to the noise generated by the spray from
the handset. The type of wall surface will affect the perceived sound levels.
Stud partition and panel walls have a tendency to resonate, whilst solid walls
provide the quietest operation. The tone of the pump motor may change when
the temperature control knob is adjusted. This is quite normal.
1.6 Inlet: 15 mm inlet compression connector is designed to accept plumbing supplies
from the top, bottom or rear.
1.7Rear entry plumbing is accommodated without the need to recess the 15 mm
inlet compression connector, enabling the wall’s surface to be completed and
sealed to prevent water ingress, before final fitting.
1.8 Swivel the inlet connector assembly to suit (not directly back into the wall). Avoid
trapping the green earth bonding wire.
1.9 Use only the 15 mm inlet compression connector supplied with the Elite ST, do
not use any other types of fitting.
1.10Outlet: 1/2" BSP male, to accept Mira flexible hose.
1.11Refrain from applying excessive force when making connections.
Note! Excessive force on the pump housing can impair pumping performance.
Make sure that the supply pipe is trimmed and bent such that the 15 mm inlet
connector sits (or can be lightly pressed) easily on the back of the clamp bracket
prior to connection with the pump housing.
1.12To avoid damage to the case when soldered fittings are used, pre-solder the
pipework and fittings before connecting them to the 15 mm inlet compression
connector.
1.13Supply pipework MUST be flushed to clear debris before connecting the
Elite ST.
10
1.14A hose retaining ring is supplied to prevent the handset from dropping below
the spillover level of the bath or shower, which could lead to contamination
from back-siphonage (refer to illustration). The supplied hose retaining ring
should meet the great majority of user requirements for shower installations
with flexible outlet fittings. However, there will be occasions when the hose
retaining ring will not provide a suitable solution. In these instances an outlet
double checkvalve, e.g. the Mira DCV-H, must be fitted. The inclusion of the
Mira DCV-H will increase the required supply pressure typically by 10 kPa (0.1
bar).
Double checkvalves, fitted in the inlet supply to the appliance, cause a
pressure build-up, which could exceed the maximum static inlet pressure for
the appliance.
1.15When installed in very hard water
areas (above 200 ppm temporary
hardness) your installer may advise
the installation of a water treatment
device, to reduce the effects of
limescale formation. Your local water
company will be able to advise the
hardness of water in your area.
1.16Avoid layouts where the hose will be
sharply kinked. This may reduce the
life of the hose.

1.17Long pipe runs and excessive use of 90° elbows will significantly reduce the
available head to supply the Elite ST. The pipework table should be completed
to ensure that adequate head is available for any given application.

2.2Electrical (checklist in detail)
2.2.1 In a domestic installation, the rating of the electricity supplier's fuse and
the consumer unit must be adequate for the additional demand. The
Mira Elite ST is a high power unit, therefore it is essential to contact
your electricity supplier to ensure that the supply is adequate for the
product. Voltage drop due to local heavy demand will reduce the shower's
performance.
2.2.2 The Mira Elite ST must be earthed by connecting the supply-cable
earth conductor to the earth terminal.
Supplementary bonding: Within the bathroom or shower room, all
accessible conductive parts of electrical equipment and extraneous
conductive parts (metal parts) that are likely to introduce earth
potential, must be electrically bonded to earth using a minimum cable
size of 4.0 mm2 if the cable is not mechanically protected, (2.5 mm2 if
mechanically protected).
2.2.3 Supply cable - refer to: 'Electrical Checklist'.
2.2.4 As a guide only, and in accordance with BS 7671 we recommend close
circuit protection:
i.e. 9.8 kW @ 240 V = 45 Amp (9.0 kW @ 230 V = 40 Amp).
It is strongly recommended that a 30 mA Residual Current Device (RCD)
is included in the electrical circuit. This may be part of the consumer unit
or a separate unit.
A separate, permanently connected supply is taken from the consumer
unit to the appliance through a double-pole switch, which has at least
3 mm contact separation. The switch can be a ceiling mounted pullcord
type within the shower room or a wall mounted switch in an adjacent
room.
2.2.5 DO NOT twist the individual cable cores of either the live or neutral
conductors, as this will prevent them from entering the terminal block.
2.2.6 DO NOT exert strain on the terminal block. Ensure that the electrical
connections are tightly screwed down.
2.2.7 DO NOT turn on the electrical supply until the plumbing has been
completed.
